Here is presented a list of shark and ray species observed and inferred to exhibit capture-induced parturition (birth). This encompasses both premature-birth and abortion of embryos. Also presented are data on species fecundity, International Union for Conservation of Nature (IUCN) threat levels, reproductive mode and fishing methods that induce parturition. If you know of a species that does not appear on the list, please get in contact with Kye Adams via so that the list may be updated. For analyses and discussion of these data please view the linked article published in Biological Conservation. If you wish to present analyses of these data please reference the dataset DOI and feel free to contact the corresponding author at with any questions. To cite a single species that exhibits capture-induced parturition please cite the original reference given. For each species the IUCN reference contains a hyperlink to the IUCN threat assessment, with information on taxonomy, geographic range, population, habitat and ecology, use and trade, threats and conservation actions. The reproductive mode for each species is taken from the capture-induced parturition reference, the IUCN threat assessment or from Compagno (1990). General references: Compagno, L.J.V., 1990.
